6. If the condition recurs, use a spare wire, if available, or provide a new wire (St. Clair P/N 200153
may be used for this purpose) for the solenoid circuit indicated by the diagnostic code.
7. If the condition persists, replace the ECU. If replacing the ECU corrects the problem, reinstall the
original (bad) ECU to confirm that the problem is in the ECU. If the original ECU now works,
inspect the ECU connectors for any corrosion or damage which may cause an intermittent
condition. If the original problem recurs, reinstall the replacement ECU.
